Calibration Window: The Calibration window (Figure 4) permits the user to access the calibration regis-
ters for each channel of the CS5532 and also perform self and system offset or gain calibrations on either
of the channels. Prior to performing calibrations however, the channel setup registers should be modified
to configure the part for the desired operating mode (see the section ‘Setup Window” on page 7 for more
details). Note that offset calibration should be performed before gain calibration to ensure accurate re-
sults. Refer to the CS5532 datasheet for more details.
